Hijackers Hamza Alghamdi and Mohamed Alshehri rent a post office box in Delray Beach, Florida. The timing is uncertain. Some reports indicate this occurs in January, which would be several months before they arrive in the US according to the FBI and 9/11 Commission (see April 23-June 29, 2001). [Washington Post, 9/30/2001; US Congress, 9/26/2002; Minneapolis St. Paul City Pages, 6/30/2004; 9/11 Commission, 7/24/2004, pp. 528] However, a document used as evidence at the trial of Zacarias Moussaoui will say the mailbox is actually rented on July 28, 2001.
